【解説】95%信頼区間とは？その限界と注意点

This video explains its meaning, basic calculation methods, and important points to note when interpreting it. This video assumes knowledge of "standard error." I would appreciate it if you could also watch that explanatory video (   • 【解説】標準誤差とは？ 標準偏差との違い・使い分け  ). Also, for the issue of "multiple testing" mentioned in the subgroup analysis section, please see here. ▶ "Multiple Testing" Explained Video:    • 【解説】多重検定の問題とは | 仮説生成と仮説検証   This is the eighth video on this channel.
